In which of the following quadrilaterals are consecutive angles always congruent? check all that apply.

Rectangle and Square.  

Step-by-step explanation:

To know if the angles of a quadrilateral is congruent you must overlap these angles one over the other, if all elements of the angles coincide, the angles are congruent; if the elements do not match, the angles are not congruent. In quadrilateral rectangle and square consecutive angles are always congruent.

In other words, two or more angles are said congruent if and only if they have the same measurement.
